Patented Feb. 6, 1934 UNiTED STATES ELECTRIC LOCK Lucien R. Baril, RiverEdge, and Joseph Ulric 7 Claims.

Our invention relates to electrically operated locking and unlockingmeans for doors or windows of a dwelling or building and for any and allpurposes for which it may be employed, and

is especially designed for simultaneously looking and unlocking both theupper and lower sash of a window, although either or both sashes of thewindow may be closed without operating Y. the lock electrically.

The prime object of the invention is to provide simple, durable,economical and thoroughly eiilcient electrically operated means disposedwithin the casing of the doors or windows so as to lock or unlock saidmeans'by making the proper contact from any safe and convenient point,such as the opposite side of the room from said doors or windows, by anyauthorized person desiring to lock or unlock the doors or a windows.

A further object of the invention is to provide means so associated withboth the upper and the lower sash of a window that, after either sashshall have been lowered or raised for ventilation purposes, both sashesmay be simultaneously locked in their adjusted position by making theproper contact by means of a push button or any suitable switch.

Another object of the invention is to so construct the latch bolt withrelation to means secured to the edge of each window sash that,

when the sashes shall have been adjusted to any desired position andlocked in such position, it will be impossible for any person seek- Ying unauthorized entrance through the window by the raising of the lowersash, or the lowering of the upper sash, but both sashes may be en--tirely closed without operating any means electrically.

Further objects of the invention are to so construct our improvedlocking and unlocking means that such means may be disposed within asuitable metallic casing, and connected by suitable wires to thelighting circuit of a building and to form a part of the regular wiringof the building, the said locking and unlocking means may besuccessfully operated by merely pushing a button suitably located at anyconvenient point, and to associate said means with a lighting circuitadapted to operate a pilot light to indicate when the door or window islocked or unlocked.

The foregoing and such other objects as may appear from the ensuingdescription are accomplished by the combination, arrangement,construction and location of the several parts hereinafter more fullydescribed and particularly pointed out in the claims appended hereto,and illustrated in the accompanying drawings, it being understood thatslight changes in the precise form, proportions and minor details of theconstruction may be resorted to without departing from the spirit orsacrificing any of the advantages of the invention.

In the accompanying drawings forming a part of this specification itwill be seen that:

Figure l is a plan partly in section illustrating the means embodyingour invention, showing said means in its unlocked position.

Figure 2 is a detail partly in plan and partly in sectional elevation,showing the latch bolt in engagement with a window sash.

Figure 3 is an elevation partly in section, showing the locking means inlooking engagement with the sashes of a window, showing said sashes intheir partly lowered and raised positions, and

Figure 4 is a cross section taken in the plane of the dotted lines 4-4,Fig. 1, showing in section a portion of the window sashes broken away.

In the embodiment of our invention as illustrated, it will be seen thatthe numeral 1 designates a metallic casing suitably disposed within thecasing of a door or window, said casing being provided with verticallydisposed partitions 2 and 2' and laterally disposed partitions 3 and 3'extending from the partition 2 to the inner side wall 4 of said casing,the partitions and side walls being formed from a single piece of metal.Suitably secured within the casing and between the partitions 2 and 2'are two electromagnets 5 and 6, one adapted to force the latch boltsinto their locked position and the other to withdraw the latch boltsinto their unlocked position through the medium of the means hereinafterdescribed.

Disposed intermediate of the two electro-magnets is a member 3 formed ofa single piece of metal formed with a large central portion 9 adapted toslidably engage the inner face of each of the partitions 2 and 2 andformed throughsaid central portion 9 is a diagonally arranged slot 10terminating with a slightly upwardly curved formation at one endthereof, and at its other end with a slightly curved downward formation,said curved formations serving to lock and maintain the latch bolts intheir unlocked and locked positions, respectively, and formed withinsaid central portion 9 is a cavity or recess for the reception of thelatch bolt operating member 12, said member extending inion wardly andprovided with a lateral extension 13 at each side of its headed portion14 and terminating with a narrowed inwardly extended portion 15 adaptedto suitably separate the locking and unlocking latch bolts 16 and toengage the headed portion 14' thereof, while through the upper end ofthe headed portion 14 of the operating member 12 is suitably secured apin 17 which projects from each side of said headed portion and isadapted to engage with the slot 10, and formed integral with each end ofthe central portion 9 is a plunger 18 which forms the movable cores forthe electro-magnets 5 and 6. Connected to an opening formed through thepartition 2 and an opening through the outer wall of the casing 1 is asleeve 19 in the outer end of which is fitted a screw threaded plugmember 20 and at its inner end portion is disposed a metallic ball 21with a coiled spring 21 disposed between the plug member and said ball,said ball being adapted to be seated in a semicircular recess formednear each end portion of the member 8, shown by dotted lines, andserving to secure said member at each end of its movement, and therebyprevent accidental movement of said member 8 in either direction,

- locking and unlocking latch bolts 16, as is clearly electrical source,said wires being suitably conthe locking magnet 5, thus causing themember as shown in Fig. 1.

It will be perceived that a coiled spring 22 is disposed between theextensions 13' and the upper end or headed portion 14 of each of theshown in Figs. 2 and 4.

It will be observed that an opening is formed through the metalliccasing through which are passed the wires 24 and 25 connected with thenected with the locking electro-magnet 5 and the unlocking magnet 6, sothat when it is desired to look a door or window it is simply necessaryto push one of the buttons 27 which will energize 8 and its cores tomove or slide downwardly, thereby causing the latch operating member toforce the latch bolts 16 into their locked position, which will bereadily understood, and when it is desired to unlock the latch boltspress the other push button electrically connected with the unlockingmagnet, thereby causing the member 8 to move in the opposite directionto withdraw the latch bolts.

When it is desired to use a pilot light in connection with ourelectrical locking and unlocking means, a light circuit is used throughthe wires 28 and 29leading to an incandescent lamp 30, and to theelectrical contact 31, formed by placing an insulation plug 32 at theend of one of the magnet plungers to which plug is secured a metallicmember 33 adapted to close the circuit through the contact 31 and lightthe lamp to indicate that the doors or windows are in locked condition,as shown in Figs. 1 and 3.

It will be understood that our improved looking and unlocking means maybe employed for all purposes for which it may be utilized, in connectionwith or without any light indicating means.

By reference to Fig. 3 of the drawings it will be seen that the windowframe 34 is broken away to show the casing 1 containing the locking andunlocking mechanism suitably disposed within said frame, and showing oneof the window sashes 35 in a lowered position and the other sash in araised position, while the latch bolts 16 are shown in their lockedposition with relation to the said sashes, with the push buttonsarranged adjacent the window frame and the indicating electric lightdisposed above the window frame.
